May 27, 2013 — Surprisingly the answer is yes. With the technology of today it is possible to use environmental friendly formic acid in fuel cell powering your mobile phone or laptop. Physicist Florian Nitze, Umeå University in Sweden, has in his thesis developed new catalysts to improve the capacity of these fuel cells. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen to run. The technology is already commercially available but formic acid fuel cells still suffer from low power and lifetime. The effect of a catalyst is to reduce the energy loss and to increase the rate of the chemical reactions, which leads to a higher ...

Growing up in Michigan, I was surrounded by some of the most beautiful natural scenery and raised to appreciate the outdoors, which led to summers on the water and many camping trips along Lake Michigan. I remember staring up into the sky pointing out to my mother what each cloud was called, showcasing what I had learned in school. The infamous game of finding the best cloud shapes that resembled real objects kept us entertained and the kids competitive. As I grew up, this stayed with me. I would always look to the sky when I was deep in thought or lost in frustration; the sky was my peace, my grounding calm. A couple years after high school, I joined the military working in ...

WASHINGTON, May 23 (Xinhua) -- U.S. researchers reported Thursday the discovery of a key molecule responsible for triggering the sensation of itch in our brain but warned that the molecule may not be a good drug target since it's involved in many body functions. Researchers at the U.S. National Institutes of Health said that there will be no itch if the molecule, a small neuropeptide called natriuretic polypeptide b, or Nppb, is taken away, but injecting it in the right place, the itch will come back. The findings, according to the researchers, show that Nppb is an essential link between the skin receptor cells that sense itching and the nerve cells that send the perception of itch ...

Our technology may be getting smarter, but a provocative new study suggests human intelligence is on the decline. In fact, it indicates that Westerners have lost 14 I.Q. points on average since the Victorian Era. What exactly explains this decline? Study co-author Dr. Jan te Nijenhuis, professor of work and organizational psychology at the University of Amsterdam, points to the fact that women of high intelligence tend to have fewer children than do women of lower intelligence. This negative association between I.Q. and fertility has been demonstrated time and again in research over the last century. But this isn't the first evidence of a possible decline in human intelligence. ...
